% WARNING: IF YOU ARE USING THIS STYLE SHEET FOR AN AAAI PUBLICATION, YOU
% MAY NOT MODIFY IT FOR ANY REASON. MODIFICATIONS (IN YOUR SOURCE 
% OR IN THIS STYLE SHEET WILL RESULT IN REJECTION OF YOUR PAPER).

% NOTICE: DO NOT MODIFY THIS FILE WITHOUT CHANGING ITS NAME. This style
% file is called aaai.sty. Modifications to this file are permitted,
% provided that your modified version does not include the acronym "aaai"
% in its name, that credit to the authors and supporting agencies is
% retained, and that further modification or reuse is not restricted. This
% file was originally prepared by Peter F. Patel-Schneider, liberally
% using the ideas of other style hackers, including Barbara Beeton. It was
% modified in April 1999 by J. Scott Penberthy and George Ferguson. It was
% modified in 2007 by AAAI. It was modified in February 2009  
% and in November 2009 by Hans W. Guesgen and Giuseppe De Giacomo. It
% was further modified in March 2010 by AAAI.
% The original preparation of this file was supported by 
% Schlumberger Palo Alto Research, AT\&T Bell Laboratories, AAAI, and 
% Morgan Kaufmann Publishers.

% WARNING: This style is NOT guaranteed to work. It is provided in the
% hope that it might make the preparation of papers easier, but this style
% file is provided "as is" without warranty of any kind, either express or
% implied, including but not limited to the implied warranties of
% merchantability, fitness for a particular purpose, or noninfringement.
% You use this style file at your own risk. Standard disclaimers apply.
% 
% Do not use this file unless you are an experienced LaTeX user. To
% satisfy AAAI's requirements, you must change your paper's configuration
% to use Times fonts. AAAI will not accept your paper if it is formatted
% using obsolete type 3 Computer Modern bitmapped fonts. Please ensure
% that your version of dvips maps to type 1 fonts. Place this document in
% a file called aaai.sty in the TeX search path. (Placing it in the same
% directory as the paper should also work.)
%
% You must also format your paper for US letter-sized paper.
% 
% There are undoubtably bugs in this style. If you would like to submit
% bug fixes, improvements, etc. please let us know. Please use the contact form
% at www.aaai.org.

%%%% named style for aaai, included here for ease of use
% This section implements citations for the ``named'' bibliography style,
% modified for AAAI use.
% This file can be modified and used in other conferences as long
% as credit to the authors and supporting agencies is retained, this notice
% is not changed, and further modification or reuse is not restricted.
% The ``named'' bibliography style creates citations with labels like
% \citeauthoryear{author-info}{year}
% these labels are processed by the following commands:
% \cite{keylist}
%  which produces citations with both author and year,
%  enclosed in square brackets
% \shortcite{keylist}
%  which produces citations with year only,
%  enclosed in square brackets
% \citeauthor{key}
%  which produces the author information only
% \citeyear{key}
%  which produces the year information only
